19 Year-Old Mistress Nova Maverick is relaxing in the hot tub with Her sl*ve, sitting on the edge to cool off while She has Her sl*ve kneeling in the hot tub, one of Her pretty pedicured feet in its mouth while the other one sits on top of its head. She wears a silver star bikini, holding the sl*ve's leash in Her hand:

"I know you p*ssed all of your sm*thering tests under My p*ssy, but - I think you cheated, sl*ve. So I'm gonna have a l*ttle AUDIT of your breath control, l*ttle b*tch!"

"What do you mean, Mistress?"

"Well - kinda like THIS!"

She suddenly pushes the sl*ve backwards into the water, standing on his body as he goes underwater. She remains standing on his body, making him c*mpletely helpless *ss the sl*ve lays sprawling on the bottom of the hot tub, in the 102-degree water under Her. She counts to 10, then pulls it up by the leash, gasping, sputtering and complaining. She says:

"That was only 10 f*cking seconds! You supposedly got up to 1 minute and a half under My p*ssy last week! Ony ten seconds should be nothing!"

The sl*ve complains that it wasn't ready, but She just pushes its head back underwater, this time with both hands. She tells the sl*ve 15 seconds as She pushes its head down and walks onto its body to ensure that it has no possible way to get up and out of the water. She starts counting down, but keeps going after 15 seconds. The sl*ve starts struggling but She pushes it down harder and slows down the count, going up to 20 seconds but more like 25. She pulls up the gasping, sputtering and coughing sl*ve, begging Her to not continue.

She pretends to give the sl*ve a rest, but then suddenly pulls up the hobble chain attached to the sl*ve's ankles, making it fall backwards and underwater as She stands on the sl*ve's body again, this time counting up to 25 seconds. She does two more dunks, getting higher and higher and sitting on the sl*ve's body while it's underwater. Finally letting up the c*mpletely spent and exhausted sl*ve, woozy from its head being in the 102 degree water, She has the sl*ve lay its head back on the side of the hot tub.

"I think we both need to cool off, b*tch, so keep your head back there, I don't want to sit on the cold dirty deck"

She climbs up on the sl*ve's body and sits on its face with Her full weight, sealing its airways closed as She starts mugging and taking selfies:

"I gotta take a few pics for My Insta account, to show My girlfriends how to get some use out of their useless boyfriends!"

She takes pictures of Her sm*thering the sl*ve with Her bikini-covered p*ssy, grinding Her *ss in its face and flaunting Her complete control and objectification of the inferior m*le. She finally finishes and leads the sl*ve over to the edge of the hot tub, standing above it, She does a final push down underwater, this time sitting on the sl*ve's shoulders underwater for a full minute. The sl*ve survives, gasping and ch*king but asks its Mistress to give it some credit and admit that it didn't cheat:

"Ok sl*ve, I guess you didn't cheat at breath training before, but I'm going to go take a shower and you will stay here, practicing your breath training and when I get back I better see you doing it with enthusiasm and for over a minute"

She pushes the sl*ve's head down underwater, steps out of. the hot tub and walks back inside to take a shower.
